Tibial torsion: cause or consequence of osteoarthritis?

Amaç: Çalışmanın amacı alt ekstremitenin torsiyonel deformiteleri ile dizde medial osteoartrit gelişimi arasındaki ilişkiyi değerlendirmek idi. Çalışma planı: Bilateral gonartrozu bulunan 19 hastanın 21 alt ekstremitesindeki femoral ve tibial torsiyon değerleri bilgisayarlı tomografi ile ölçülerek incelendi ve sağlıklı 8 olgunun 14 alt ekstremitesi ile karşılaştırıldı. Bulgular: Alt ekstremitesinde gonartroz olan ve olmayan olgular arasında tibial torsiyon (sırasıyla 26.20°±9.78° ve 25.32°±11.50°), femoral torsiyon (sırasıyla 15.89°±8.63° ve 13.91°±7.26°) ve tibiofemoral indeksi (sırasıyla 10.30°±13.06° ve 11.39°±12.84°) açısından anlamlı bir fark bulunmadı (p>0.05). Çıkarımlar: Erken artritik dönemde görülen medial kompartman osteoartritinin alt ekstremitedeki torsiyonel deformitelerle her zaman ilişkili olmadığı sonucuna vardık.

Tibial torsiyon: Osteoartritin sebebi mi, sonucu mu?

Objective: The purpose of this study was to evaluate the relationship between torsional variations of the lower extremity and the development of medial osteoarthritis in the knee. Methods: Computed tomography measurements of the femoral and tibial torsion were evaluated in 21 lower extremities of 19 patients with primary bilateral gonarthrosis and compared with 14 lower extremities of eight normal individuals. Results: There was no statistically significant difference between lower extremities with and without gonarthrosis in terms of tibial torsion (26.20°±9.78° and 25.32°±11.50°, respectively), femoral torsion (15.89°±8.63° and 13.91°±7.26°, respectively) and tibiofemoral index (10.30°±13.06° and 11.39°±12.84°, respectively) (p>0.05). Conclusion: We conclude that medial compartment osteoarthritis in the early arthritic period is not always associated with torsional deformities of the lower limb.
